The epidemiology, clinical signs, and pathology of 42 outbreaks of enzootic calcinosis (EC) in cattle, sheep and goats in Mato Grosso (19), Distrito Federal (19), Goiás, (6), Minas Gerais (2) and Tocantins (1), Brazil, [date not given] are presented. Additionally, Ageratum conyzoides, Chamaecrista desvauxii [Cassia desvauxii], Cissus erosa, Elephantopus mollis, Eragrostis sp., Eupatorium odoratum [Chromolaena odorata], Hymenaea courbaril, Jatropha sp., Ludwigia octovalvis, Mimosa hirsutissima, Murdania nudiflora, Rhynchanthera novemnervia, Scoparia dulcis, Sida santaremensis, Tibouchina sp., Vernonia brasiliana, Waltheria sp., Arachis sp., Cnidoscolus cnicadendron, Eleusine tristachya, Ludwigia leptocarpa, Ludwigia sp., Mimosa pellita, Sida cerradoensis, Sida ciliaris, Sida spinosa and Vernonia ferruginea as the possible causes for the outbreaks were experimentally administered to rabbits and sheep. It was shown that none of the 33 rabbits and 14 sheep that ingested the selected weeds to detect calcinogenic effect of the plants developed clinical changes, and mineralization of soft tissues was not observed during necropsies or histologic examination. Serum Ca and P concentrations were within normal values.

Somatic-cell nuclear transfer is a cloning technique that enables the creation of a viable embryo from a donor adult to produce a genetically identical individual. This technique opens numerous potential possibilities for medicine and animal reproduction. However, several reports have documented cloning-related issues. Embryo and fetal losses remain significantly higher than in other techniques, and there is a high incidence of dystocia and hydrops, which decreases efficiency and increases costs. Animals delivered at term often exhibit a syndrome known as macrosomia and experience difficulties in adapting to life outside the uterus, and death is a common outcome. In the present study, 41 cloned calves that died in the neonatal period were subjected to gross and histopathological examination. Most important gross lesions were found in the liver (enlargement, congestion, yellowish color), kidneys (brownish color at surface and cut, and cysts), lungs (atelectasis, parenchymal consolidation, and secretions in bronchi and bronchioles), and heart (concentric and eccentric hypertrophy, hematic cysts, persistence of ductus arteriosus). Primary microscopic findings were seen in the liver, kidneys, and lungs from neonatal calves. In the liver, 85% of the animals exhibited hepatic degeneration. The presence of a brownish pigment within the cortical tubules of the kidneys was found in approximately 90% of the samples; the presence of this pigment has not been previously reported in cloned calves. In the lungs, a large number of animals exhibiting lesions characteristic of pneumonia (55%). These changes were the pivotal causes of death, mainly due to problems in adapting to life outside the uterus and opportunistic infections in the neonatal period. Further investigation focusing on pathological anatomical changes is necessary to map these abnormalities in cloned animals.

Primary gallbladder neoplasms occur infrequently in domestic animals and rarely in wild animals. This article describes a case of gallbladder adenoma in a mongoose
